What's in an entrepreneur's motto? Insight into their motivation, get-it-done attitude, and drive to succeed.

We are drawn to motivational quotes (this conclusion is based on my entirely unscientific observation of tweets and retweets since 2008), but what are the words of wisdom entrepreneurs work by day in and day out? What jump starts their day and focuses their energy? Since taking an active interest in my investment portfolio and becoming an angel investor in 2012, my motto has been "Invest in the Change You Want to See in the World." As someone known for her knack with networking, my regular guidance is "Stop Committing Random Acts of Networking." These words fuel how I spend my time, money, and energy.

From interviews conducted over a year, here are the daily mantras of 35 entrepreneurs to inspire you as you tackle a looming challenge or rally your energy to reach for that next big milestone:
